ivtv-0.10.0 has a new feature where you can obtain an index into the
mpeg file from the card's hardware. That way you can very cheaply
determine where each frame begins in the mpeg file. That's very nice,
but it looks as if sometimes the index in the card's ringbuffer gets
corrupted. At least, that's what this message indicates.
Can you tell whether these messages appeared directly when the recording
started? Are they only intermittent? In the log excerpt I see a gap
between the first and second warning, but I can't tell how it
continuous afterwards.
Thanks,
Hans
